High-quality stainless steel master link for 3 or 4 hook suspension.
You can connect the chain using a connector.
Improve on-site efficiency with a wide range of options tailored to crane widths! Please consider it before an accident occurs.
The chain sling sets used in the manufacturing and construction industries require selecting dimensions that allow free movement within the hook of the overhead crane, as well as choosing the master link. If the master link is significantly smaller than the hook, concentrated loads can occur at the corners of the link, which is very dangerous. A width of the crane hook multiplied by 1.2 or more is necessary. Please select a dimension that allows the master link to move freely within the hook. 【Features】 - A variety of master links corresponding to the width of the crane - Child links included as standard, making hardware selection easy *For details, please contact us or download the catalog.

High load-bearing capacity and corrosion resistance.
The stainless steel master link combines high load capacity, corrosion resistance, and ease of operation. It is manufactured through high-precision machining, making it ideal for use in hygienic environments such as clean rooms, food processing, meat processing, chemical, and pharmaceutical industries. Additionally, it demonstrates long-term durability in seawater and acidic environments (offshore applications, acid pickling lines, etc.). There are variations for "single and double lifting" and "triple and quadruple lifting," allowing for selection based on application. The stainless steel used in the product exhibits excellent corrosion resistance even in harsh environments such as chemical agents, saltwater, and high temperatures.
Suppress overall deformation of the fill soil and achieve cost reduction with a low improvement rate! Examples of construction are also introduced with photos.
The "Low Improvement DMM Method" is a construction technique that places improved columns across the entire width in the transverse direction, which can suppress overall deformation of the embankment and allows for cost reduction by using a low improvement rate (by widening the spacing of the improved columns). When ground improvement is carried out at a low improvement rate, issues such as differential settlement between the improved and unimproved areas may arise, necessitating surface treatment as a countermeasure. For surface treatment, geosynthetics (Paralink) installation and shallow improvement methods are effective. [Selection of Geosynthetic (Paralink) Standards] ■ Determination of target differential settlement amount ■ -1 Calculation of proportional coefficient α ■ -2 Determination of tensile rigidity EA ■ Confirmation of tensile strength ■ Determination of required part numbers *For more details, please refer to the PDF materials or feel free to contact us.
![Wire joint fittings Fast Link [Contributes to labor saving]](https://image.www.ipros.com/public/product/image/61a/2000650749/IPROS91104395229283754083.jpeg?w=280&h=280)
No need for wire clips or turnbuckles! You can easily connect and secure wire ropes.
By simply inserting the wire into the fast link, it will not come out in the reverse direction. You can connect and secure the wire quickly and easily. In case of failure, you can easily re-tension it using the release tool. (Applicable only for wire joiner adjustable and fence ender) Using a dedicated tension tool allows you to securely tension the wire. This can streamline the installation of wire mesh fences, vineyards, orchards, and wire fencing for wildlife damage prevention.
This is a new type of solar construction light that simultaneously flashes multiple lights (synchronized alternating flashing) to mark the construction area in the shape of a line.
The standard time radio waves for clocks (Fukushima and Saga) are received, causing multiple construction lights to flash simultaneously. - Synchronization flashing function: By having multiple construction lights flash at the same time, the construction area is displayed in a linear shape, enhancing visibility. This allows for clear indication of the construction area, especially at night or in poor visibility conditions. - Solar rechargeable: It can be charged using the solar panel installed on the top of the unit. It can continue to flash for about 15 days even without sunlight, making it less susceptible to weather conditions. - Durability and waterproof structure: Made of reinforced polycarbonate and featuring a waterproof design, it can be safely used in various environmental conditions. - Easy installation: It can be directly attached to perforated cones such as safety cones and road ring cones, and can also be easily installed on single pipes using a single pipe vice.

Efficient lifting operations are possible with shortening (length adjustment function)!
This is a master link with a shortening function specifically designed for double lifting, capable of handling loads from 1.5t to 13.8t (within a usage angle of 90 degrees). With just this one master link, you can adjust the length of any chain to the optimal lifting height. The method is simple: just hook the chain into the length adjustment pocket located at the bottom of the product to change the length. This allows for the balanced lifting of unbalanced loads (eccentric loads).
Bluetooth exclusive! Ultra-lightweight and compact design at 1.5kg!
The true weight of the suspended object cannot be determined until it is measured. The Bluetooth wireless load cell, BlueLink "BLD" from Martec, alleviates that concern. It supports a load capacity of 6.5 tons. Measurement is possible with the smartphone app "HHP Display App" within a wireless transmission range of up to 100 meters (up to 8 devices can be connected simultaneously). An overload alarm (90dB) can be set, and it includes peak hold / tare function and load unit selection. Additionally, measurement data can be output in CSV and PDF formats. Our calibration center provides calibration and inspection services. For more details, please contact us.
